Abstract
Method and apparatus for providing a welded attachment between components for a disk drive head suspension where the material of at least one of the components is not suitable for welding directly to the material of the other component. The method and apparatus include providing at least one insert in an aperture in one component compatible with material of the second component or an insert in the second component to enable the first component to be welded to the second component. The insert may be an interference fit in the aperture or it may be coined to enhance retention. Fully hardened or annealed stainless steel may be used for the insert, and aluminum, ceramic or a polymer or composite may be the material receiving the insert. The aperture may be preformed or formed in by the insert during the operation of punching and installing the insert.
